The efficacy and safety of a third anti-TNF monoclonal antibody in Crohn's disease after failure of two other anti-TNF antibodies.

BACKGROUND: Adalimumab (ADA) and certolizumab pegol (CZP) have demonstrated efficacy in Crohn's disease (CD) patients previously treated with infliximab (IFX). AIM: To assess the efficacy and tolerability of a third anti-TNF in CD after failure of and/or intolerance to two different anti-TNF antibodies. METHODS: Crohn's disease patients who received ADA or CZP after loss of response and/or intolerance to two anti-TNF agent were included in this retrospective study. Data were collected using a standardized questionnaire. Clinical response, duration, safety and reasons for discontinuation were assessed. RESULTS: Sixty-seven patients treated with CZP (n = 40) or ADA (n = 27) were included. A clinical response was observed in 41 (61%) at week 6 and 34 patients (51%) at week 20. The probability of remaining under treatment at 3 months, 6 months and 9 months was 68%, 60% and 45%, respectively. At the end of follow-up, the third anti-TNF had been stopped in 36 patients for intolerance (n = 13), or failure (n = 23). Two deaths were observed. CONCLUSIONS: The treatment with a third anti-TNF (CZP or ADA) agent of CD patients, who have experienced loss of response and/or intolerance to two anti-TNF antibodies, has favourable short-term and long-term efficacy. It is an option to be considered in patients with no other therapeutic options.

Association of ECG abnormalities and incident heart failure events

Background: With the aging of the population, the heart failure (HF) incidence and prevalence trends are expected to significantly worsen unless concentrated prevention efforts are undertaken. ECG abnormalities are common in the elderly but data are limited for their association with HF risk. Objective: To assess whether baseline ECG abnormalities or dynamic changes are associated with an increased risk of HF. Method: A prospective cohort study of 2915 participants aged 70 to 79 years without a preexisting HF followed for a median period of 11.4 (IQR 7.0-11.7) years from the Health Aging and Body Composition study. The Minnesota Code was used to define major and minor ECG abnormalities at baseline and at 4-year. Main outcome measure was adjudicated incident HF events. Using Cox models, the (1) the association between ECG abnormalities and incident HF and (2) incremental value of adding ECG to the Health ABC HF Risk Score, was assessed. Results: At baseline, 380 participants (13.0%) had minor and 620 (21.3%) had major ECG abnormalities. During follow-up, 485 (16.6%) participants developed incident HF. After adjusting for the eight clinical variables in the Health ABC HF Risk Score, the hazard ratio (HR) was 1.27 (95% confidence interval [CI] 0.96-1.68) for minor and 1.99 (CI 1.61-2.44) for major ECG abnormalities (P for trend <0.001) compared to no ECG abnormalities. The association did not change according to presence of baseline CHD. At 4-year, 263 participants developed new and 549 had persistent abnormalities and both were associated with increased HF risk (HR = 1.94, CI 1.38-2.72 for new and HR=2.35, CI 1.82-3.02 for persistent compared to no ECG abnormalities). Baseline ECG correctly reclassified 10.6% of overall participants across the categories of the Health ABC HF Risk Score. Conclusion: Among older adults, baseline ECG abnormalities and changes in them over time are common; both are associated with an increased risk of HF. Whether ECG should be incorporated in routine screening of older adults should be evaluated in randomized controlled trials.
